ある。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electrostatic recording medium, and in particular to a CA
The present invention relates to an electrostatic recording medium suitable for a color electrostatic printer/plotter that outputs color drawings in a D (Computer Design) system.

せて記録を得るものである。An electrostatic recording medium is made by providing a dielectric layer made of an insulating resin and a pigment on a conductive support that has been subjected to conductive treatment.
An electrostatic latent image is formed by applying voltage to the surface or both sides of the dielectric layer, developed with toner (colored powder or liquid developer), and then fixed by heat, pressure, drying, etc. to obtain a record. It is.

より解像度の点でも優れた特徴を有する。Electrostatic recording media have excellent recording speed and G8 record storage properties,
By using recording electrodes with a high resolution of 16 dots/w, it also has excellent resolution.
また、ＣＡＤ用の大型プロッターとして、静電プロッタ
ーはペンプロッタ−に比べ記録スピードが速く、大量の
図面を出力する場合に好適である。Further, as a large plotter for CAD, an electrostatic plotter has a faster recording speed than a pen plotter, and is suitable for outputting a large number of drawings.

ラフィックスの出力等に利用されている。Furthermore, in recent years, color electrostatic printers have been used not only for creating blueprints for buildings, precision instruments, integrated circuits, and other objects, but also for enlarging copies of aesthetic paintings, photographs, and printed matter, and outputting computer graphics.

ある。このためには誘電層表面と電極との間隔を適性に
保つ必要があり、適当な粒径をもつフィラーを絶縁性樹
脂と混合し、誘電層を形成する必要がある。The records output to the electrostatic plotter mainly include a solid area filled with toner and a thin line record area. In solid areas, it is necessary that the recording uniformity is good, the recording density is high, and there is no staining (fogging) due to excess toner adhering to areas other than the recorded areas. In the thin line recording section, it is necessary that there be no thin line gaps where thin lines are interrupted midway, or abnormal dots where the dot diameter is 3 to 5 times larger than a normal dot. For this purpose, it is necessary to maintain an appropriate distance between the surface of the dielectric layer and the electrodes, and it is necessary to mix filler with an appropriate particle size with an insulating resin to form the dielectric layer.
モノクロ静電記録の場合は、静電潜像を形成する電極と
黒色のトナーを供給する現像部のみであり、１回の記録
中だけ、誘電層表面と電極表面との間隔を適性に保持し
ていれば良い。In the case of monochrome electrostatic recording, there are only electrodes that form an electrostatic latent image and a developing section that supplies black toner, and only during one recording, the distance between the dielectric layer surface and the electrode surface is maintained appropriately. It's fine as long as it's there.
一方、カラー静電記録の場合には、３原色（シアン、マ

組あり、記録紙は１回通紙されるのみのシングルパス方
式がある。On the other hand, in the case of color electrostatic recording, there are four developing devices that supply toner of three primary colors (cyan, magenta, yellow) and black toner, and recording is performed one color at a time. In this case, there is a multi-pass method in which one electrode moves the recording paper back and forth multiple times, and a combination of an electrode and a developer is used in four ways for each color.
There is a single-pass method in which the recording paper is passed only once.
両方式とも中間色をデイザ法（面積制御法）によって表
現し、フルカラーを実現している。Both types express intermediate colors using the dither method (area control method) to achieve full color.
この場合、記録紙は各色の記録中にも誘電層表面と電極
表面との間隔を適性に保っておく必要がある。In this case, it is necessary for the recording paper to maintain an appropriate distance between the dielectric layer surface and the electrode surface even during recording of each color.

まう。However, each time the recording paper is used to record each color using a color electrostatic plotter, 10
When the surface of the dielectric layer is pressed against the electrode part under a load of 0 g to 300 g, the smoothness of the surface of the dielectric layer increases. In addition, after being immersed in a toner solution that is mainly made of isoparaffinic petroleum solvent and developed, the excess toner solution is removed by suction with a 600-800 mm LD and rubbed with an edge, which further improves the smoothness. rises. This process is repeated four to five times in color electrostatic plotters, resulting in a narrowing of the distance between the dielectric layer and the pin electrode.

品質の画像を得るために必要である。Due to the above differences, when conventional monochrome electrostatic recording paper is used for color recording, missing fine lines, abnormal dots, and poor uniformity especially in solid areas occur, resulting in insufficient full-color images. There were no drawbacks. Compared to the conventional monochrome version, the color version has more abnormal dots,
Reducing line skipping and improving uniformity is necessary to obtain higher quality images.

The purpose is to provide

０秒の範囲になるようにした静電記録体である。That is, the present invention provides an electrostatic recording material in which a conductive layer and a dielectric layer are sequentially provided on at least one side of a support, in which the blending ratio (by weight) of the resin of the dielectric layer and the filler having an average particle size of 0.5 to 20 μm is ratio) is 515 to 9/1, J, TA
The Oken type smoothness of the surface of the dielectric layer before recording was measured according to PPI Paper Pulp Test Method No. 5 from 20 seconds to 70 seconds, and in order to take into account the increase in smoothness during color electrostatic plotter recording, The roll in contact with the dielectric layer is coated with an isoparaffinic petroleum solvent, such as Isopar G (boiling point 158-1
77°C; manufactured by Etsuji Co., Ltd.) or Isopar H (boiling point 174
℃ ~ 188℃; by a machine calender immersed in EDGE Co., Ltd.) Pressure was applied once at 500 g per 1 cm paper width, and after drying, the Oken type smoothness of the dielectric layer was 50 seconds to 17.
This is an electrostatic recording material designed to be in the range of 0 seconds.

色とも良好な画質を得ることが出来る。The recording medium coated to meet the above conditions has an Oken type smoothness of 30 to 140 seconds after recording with a color electrostatic plotter, and is good in both single colors of all four colors, heavy colors of all four colors, and intermediate colors. You can get good image quality.

。If the smoothness before passing through the plotter is less than 20 seconds, taking the uniformity of a single color solid area as an example, in the order of Y → M → C → Bk, there will be more points where toner does not adhere to the recording surface, resulting in poor uniformity. becomes defective. Furthermore, the number of missing thin lines increases and the recording quality deteriorates.

In the order of C9M-Y, toner adhesion to the recording surface was uneven due to frost yielding (
ffi (small white spots), resulting in poor uniformity. The uniformity of the overlapping color area is such that the first single color output (for example, C in the case of C+M) uniformly covers the recording surface without any omission, and the second color (for example, M in the case of C+M) covers the top of the first color. However, it has the disadvantage of uneven frost yield.

ない。The dielectric layer of the present invention is composed of a filler and an insulating resin. The dielectric layer filler preferably has an average particle size of 0.5 to 20 μm in order to maintain an appropriate distance between the dielectric layer surface and the electrode surface. In addition, it is desirable that the dielectric layer filler is relatively hard and has a low rate of increase in smoothness due to friction, such as zinc oxide, titanium oxide, calcium carbonate, silicic acid, silicate, fired clay, aluminum hydroxide, barium sulfate, lithopond, etc. Inorganic pigments such as epoxy resin powder, melamine resin powder, phenolic resin powder, starch powder, cellulose powder and other organic pigments can be used. Inorganic pigments with a Mohs hardness of 2 or less, such as clay talc and mica, and organic pigments with relatively low hardness, such as polyethylene powder and polypropylene powder, are undesirable.

A content of 10 to 30% of the resin and methacrylic resin is permissible in order to improve the fixing properties of the toner, but a content exceeding 30% is undesirable because it promotes an increase in the smoothness of the dielectric layer.
